67	Mon Mar 30 01:43:58 2020	Ragan	General	First measurement with 206Pb81+ beam pattern details	The following shows the pattern for first measurement in ESR (gas jet is on for = 60*5 secs = 300 secs as it can be seen on step
68	Mon Mar 30 02:00:46 2020	Ragan	Runs	First measurement with 206Pb81+ beam	beam: 206Pb81+ energy: 400 MeV/u
69	Mon Mar 30 02:27:44 2020	Ragan	Runs	Second measurement with 206Pb81+ beam at I_cooler = 200 mA	I_cooler = 200 mA beam: 206Pb81+
74	Mon Mar 30 04:15:29 2020	Ragan	General	Second measurement with 206Pb81+ beam at I_cooler = 200 mA	In the picture below, a very nice storage of 206Pb81+ at 200 mA electron cooler current for no gas jet target can be seen in ESR.
76	Mon Mar 30 06:15:13 2020	Ragan	Runs	Second measurement with 206Pb81+ beam at I_cooler = 20 mA	I_cooler = 20 mA beam: 206Pb81+

79	Mon Mar 30 06:34:47 2020	Ragan	General	Second measurement with 206Pb81+ beam at I_cooler = 20 mA	In the ESR picture below, the decay of beam is very fast initially for few minutes and then the decay is constant. But why does
103	Mon Mar 30 20:51:06 2020	Ragan	Detectors	Bias Voltage for Si-pads	The limit of the leakage current for all Si pads was increased from 1500 nA to 5000nA and
107	Tue Mar 31 20:32:05 2020	Ragan	General	203Tl80+ 200Hg79+ 205Tl81+	Below in the schottky spectrum, on left is 203Tl80+ contamination, in middel is 200Hg79+ contamination and on right most is 205Tl81+.
108	Tue Mar 31 20:50:05 2020	Ragan	General	200Hg79+ 205Tl81+	203Tl80+ impurity is removed by moving scrapper inside ESR. Only 220Hg79+ is left now
109	Tue Mar 31 21:07:05 2020	Ragan	General	Separation of 203Tl80+ and 200Hg79+ using scrapper in ESR	It can be seen in the video how 203Tl80+ (on extreme left) and then 200Hg79+ (in middle originally) is separted from 205Tl81+ by
